Checkbox Filtering Using MooTools ElementFilter

When I first wrote MooTools ElementFilter, I didn't think much of it. Fast forward eight months later and I've realized I've used the plugin a billion times. Hell, even one of the "big 3" search engines is using it for their maps application. There's one more place I'd like to use it. My employer uses a basic SPAM filtering system which allows me to see emails that were incorrectly (or correctly) caught in SPAM, click a checkbox, and click a "Deliver" button. The problem is that it will catch a bunch of valid emails with very similar subject lines, so I have to hunt down all of the emails, check the email's checkbox, and keep searching. Inefficient to say the least. That's why I've used ElementFilter to find LABEL elements with the given search text and automatically check their checkboxes.

A while back I debuted a tasteful mouseover/mouseout technique called link nudging. It started with a MooTools version and shortly thereafter a jQuery version. Just recently Drew Douglass premiered a jQuery plugin that aimed at producing the same type of effect.
